What Q4323 covers

Q4323 identifies the AlloPly wound-care graft product by the area supplied, rather than the clinician’s work to prepare or treat the wound. It may be used in outpatient wound care, including treatment of chronic diabetic foot or venous leg ulcers when the clinician selects this product. The clinician performing the application may be a physician or another qualified practitioner, depending on the setting and applicable coverage rules.

Report Q4323 with the primary skin-substitute application procedure, selecting that procedure by the wound site and treated area. Units should reflect the square-centimeter quantity represented by the product documentation and claim. The record should identify AlloPly, the wound treated, and the amount used. CMS treats Q4323 as an add-on paid within the primary procedure’s global period. It is technical-component-only; a separate code covers interpretation. Its PFS valuation has no physician work or malpractice RVUs.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

Q4322 identifies Caregraft, not AlloPly. Select the product code from the graft actually furnished.

Q4323 billing questions

What procedure should be reported with Q4323?

Report it with the primary procedure for applying the skin substitute graft. Choose the application code based on the wound site and treated area.

How are units determined?

The descriptor is per square centimeter, so the claim quantity should reflect the documented AlloPly area represented. Keep product and wound-area records that support the quantity billed.

Can Q4323 be reported by itself?

No. CMS identifies Q4323 as an add-on code that must be billed with a primary procedure.

Does Q4323 include the graft application work?

Q4323 identifies the AlloPly product, while the primary application procedure reports the graft-placement service. CMS places payment for Q4323 within that procedure’s global period.

How does the technical-component designation affect billing?

CMS classifies Q4323 as technical-component-only, with a separate code covering interpretation. The product line itself does not report the interpretation.

How is Q4323 distinguished from Q4322 or Q4324?

Those codes identify different named wound-care products. Report the HCPCS code matching the product actually furnished, rather than choosing among them by wound size.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
